Question:
I wish to create a lab with a a small pith ball and an
E-field. I would like to suspend a pith ball in an E-field and watch it deflect
like a pendulum and measure the angle.
My problem is how can I create an E-field? any ideas?
Replies:
Take an aluminum pie pan and tape an insulator handle (wood or plastic) to
the inside as a handle. Charge up a latex balloon with fur. Transfer the
charge from the balloon to the pan. That should work. If you have an
electrophorous instead of a balloon, that will work, too.
